Building a Qualitative Frequency Table:
1) See START HERE. All tables start out as values counted in to categories.
2) List the categories of the variable (Color).
3) List the frequency (f) of each category and a total sum.
4) Calculate the relative frequency of each category by dividing the frequency of the category by the total.
5) Add a title and any other information that may aid in understanding the table.
Categories: Data values distinguished by a non-numeric quality (Blue, etc.)
Total f: the sum
of all frequencies
Total rf:
will sum to 1.00
